SSM2044 as stand-alone vcf module?

Just wondering if it would be possible to build the SSM2044 as a stand-alone VCF module, or does it need the control board to operate properly?

Yes, with a sidekick board. Unfortunately they are no longer produced by MI. You might be able to grab a used one of someone, or get a PCB made by a PCB fab house though…

YOu could as well just wire 2 10k lin pots to the Q and F CV lines…

…or you could connect pwm outputs from an Arduino board to Q, F and VCA
